urllib2 problem with ports.

[Ant]

Hi all,

I have just moved to a new machine, and so have installed the latest
version of Python (2.4.3 - previously I believe I was running 2.4.2).
Unfortunately this seems to have broken urllib2...

An app I wrote for testing our web application makes heavy use of
urllib2 against the localhost, and I am getting the following problem
(minimal code sample):

#/usr/bin/python
import urllib2

urllib2.urlopen("http://localhost:8080/")

This gives the output (Stack trace snipped - can post if required):

urllib2.HTTPError: HTTP Error 502: Proxy Error ( The Uniform Resource
Locator (U
RL) does not use a recognized protocol. Either the protocol is not
supported or
the request was not typed correctly. Confirm that a valid protocol is
in use (fo
r example, HTTP for a Web request). )

This I believe is a problem with the addition of a non-default port.
Replace the url with "http://google.com" for example, and all is well.

Any ideas for workarounds? Or do I roll back to 2.4.2?

that's not a Python error, so that won't help.

check your proxy configuration. most likely, your new machine is set up
to route all requests via a remote proxy.

(on windows, you'll find the proxy configuration under "Internet
Options" - "Connections" - "LAN Settings". before you do anything else,
make sure "Bypass proxy server for local addresses" is checked)

Here's me looking like a fool The parts of the machine (eg Firefox,
GAIM etc) that I'd set up use a direct connection - it looks like the
guy who'd had the machine before me used a proxy with IE...

Interestingly the "Bypass proxy server for local addresses" was
checked. Anyway, I've changed it to a direct connection, and all seems
well. Thanks.
